answered-by-expert Expert Answer

Centre of gravity is a point at which the gravitational force on a body effectively acts.

It is the sum of the gravitational force acting on all the individual atoms of the body.

You can think of a body made up of a large number of small elements. Each of these elements is pulled down by the earth. A single  point at which a force  equal to the sum of these forces acts, is called the centre of gravity.

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
